In this study, we attempted to investigate the role of dichotomous thinking (DT) as the cognitive mechanism of mood fluctuation that is a core symptom of Bipolar Disorder (BD). We tried to explore whether DT that divides things and objects into two mutually exclusive categories may amplify the mood fluctuation in BD. To access the mood variability occurring in daily life, mood diary was adopted. From the population of cyber university students, 63 subjects were screened through Mood Disorder Questionnaire (MDQ) and Dichotomous thinking Index-30 Revised (DTI-30R). They were assigned to four conditions according to the factorial design of pathology group (bipolar/control) by mechanism (high/low DT). Subjects kept the mood diary for 14 days. As results, the prediction that bipolar students with high DT may show wider variability of mood than controls was confirmed. However, detailed results were different according to mood valence. The effect of DT to amplify the mood fluctuation in BD was confined to negative mood, and was not supported in positive mood. The ups and downs of negative mood was more intense in bipolar group with high DT. That is, it is not the bipolar tendency per se, but the effect of DT in the context of bipolar tendency that produces variability of negative affect. On the other hand, the fluctuation of positive mood across 14 days was stronger in bipolar group than control group regardless of DT. Finally, the theoretical and clinical implications were discussed, and the limitations of present research with the directions for future ones were presented.
